DISPENSING DEVICE.

Application filed August 28, 1922. Serial No. 583,837.

To all whom it may concern:

Be it known that I, ALEXANDER HAMIL- TON Ponx, citizen of the United States, residing at Pi Point, in the county of Nansemond and State of Virginia, have invented certain new and useful Improvements in Dispensin Devices, of which the following is a speci cation.

This invention relates to an improved dispensing device, being particularly designed for use by druggists or the like and seeks as one of its principal objects, to provide a device whereby heavy or viscous oils or fluids may, without spilling, be readily emptied from a large container into a smaller container.

The invention has a further object to provide a device which may be readily attached to different containers and operated for discharging the contents thereof.

And the invention has as a still further object to provide a device which will be characterized by structural simplicity and which will be adapted for a wide range of use.

Other and incidental objects'will appear hereinafter.

In the drawings:

. Fi re 1 is a vertical sectional view showmg my improved dispensing device in connectlon with a conventional container, and

Figure 2 is a detail elevation of the stopper or closure member of the device.-

In carrying the invention into efi'ect. I employ a stopper or closure member 10 tapered towar its inner end. This stopper is preferably formed of soft rubber and is stepped to provide a series of longitudinally spaced circumferential flanges or lips 11 having flexible upwardly directed feather 1y increasing indiameter from the inner end of the stopper toward the outer end. Slidable through the stopper is a discharge pipe 12 provided at its inner end with a laterally directed terminal 13 while the outer end portion of said pipe is curved laterally and is formed with a depending nozzle 14. Interposed in the discharge pipe near the nozzle is a suitable shut-off valve 15. Fixed upon the stopper to extend therethrough is an air pipe 16 extending above and beneath the stopper and connected to said ipe is an appropriate rubber air bulb 17 aving a suitable intake valve 18 as well as check valve 18 wall.

and provided with a flexible discharge tube i2 fittlng over the upper end of the pipe In Figure 1 of the drawings, I have shown my improved dlspensing device in connection with a convenional bottle or container 20.

As illustrated, the stopper 10 is forced into the neck of the bottle for closing the bottl e airtight and supporting the discharge pipe 12 to extend downwardly into the bot tle. In this connection, it is to be observed that when the stopper is thus forced into the neck of the bottle, the lips 11 of the. stopper will be compressed or flattened upwardly against the wall of sa1d neck to lmpinge at their free edges thereagainst for resisting outward movement v of the stopper so that accidental dislocation of the stopper will be prevented and, due to. the extreme resiliency of the stopper, the stopper being, as previously indicated, preferably formed of soft rubher, the stopper may be readily forced into bottle necks of different sizes, thus adaptm the device for a relatively wide ran e 0 use. By opening the valve 15, the bu b 17 may be operated for forcing air into the bottle and expelling the contents there-, of through the discharge pipe 12. Accordm (liy, the contents of the bottle may be rea ily emptied therefrom and by closing the valve 15 spilling of said contents may be easily prevented. In the present instance, I have shown a concavo-convex bottom wall upon the'bottle 20 and, as will be seen, in providin the terminal 13 .upon the discharge plpe 12, said terminal will extend to a point near the side wall of the bottle while by slidably adjusting said pi e through the stopper, the lower end of t e pipe may be disposed close to the bottom Accordingly, practically all. of the contents of the bottle may be emptied therefrom.' Furthermore, in adjustably mounting the pipe upon the stopper, the efi'ective length of the pipe below the stopper ma be varied to suit difi'erent containers. owever, as will be seen, the laterally directed end portions of the pipe will serve to pre vent the ipe from ecoming accidentally detached rom the stopper. I

Havin thus described the invention,

what is c aimed as new is:

1. The combination with a container having a dischar e neck, the inner wall of which is smooth an unobstructed, of a truncated against the smooth wall of the neck of the container andcompressed thereagainst to form an air and liquid-tight joint between the parts.

2. The combination with'a container having a discharge neck, the inner wall of which is smooth and unobstructed, of a rubber stopper fitting within the neck of the container and a ertured lon itudinally to accommodate air and liqui discharge pi es therethrough, said stopper being providbd .with a longitudinally extended series of step ed circumferential elastic lips succesa sive y increasing in diameter from the 3. lower end to the upper end of the stopper and having their free edges relatively thin and directed upwardly and adapted to be compressed by contact with the smooth wall of t e neck of the container to form an air and liquid-tight joint between the parts.

, '3. In a dispensing device, a truncated conical rubber stopper apertured longitudinally to accommodate air supply and liquid discharge pipes therethrough and provided with a series of relatively narrow upwardly directed circumferential elastic lips terminating in feather edges adapted'to be compressed against the smooth inner wall of the neck ofa container when the stopper is inserted therein to prevent the escape of air or liquid from said container.

In testimony whereof I aflix my signature.

ALEXANDER HAMILTON POLK.
